This signaling apparatus is one that to be struck by the coin in Its descent. To is operated by mechanical means as distinthe signal-plate are secured the bells 70 7t k k and a chime several of the bells projecting into two separate coin-channels. The bell 70, for instance, presents one edge in position to be struck by a ten-cent piece, while its other edge is presented in such position as to be struck by a five-cent piece, while each of the separate coins are moving in their appropriate guides or channels. The coin-channel appurtenant to the ten-cent piece is arranged so that the bell k is struck near the beginning of the descent of the coin, and at a later period of time the bell 7c is struck by the same coin, thus designating by the sounding of two separate signals the fact of the payment of the ten cents. The five-cent coin strikes but a single note to indicate the payment of that amount.

It is desirous that a certain interval of time should elapse between the striking of two signals by any given coin, and in order to provide for the necessary delay in the descending motion of the coin the opposite walls of the guideway or channel may be provided with a series of indentations, as shown in Fig. 2, so that a coin moving from one to the other across the channel is delayed in its descent a sufiicient time, depending upon the number of such indentations Z. Another means for providingfor the delay is illustrated in the curved channel or guideway provided for the fifty-cent piece, the coin, after having struck the first bell k following a zigzag course down the channel before it reaches the bell 7.2

In order to prevent any rattling of the coins in the channels or guideways, narrow tracks m are preferably provided, so that the coin is lifted out of contact as to the greater part of its surface with the side walls of the guideways. Several of the channels (those for the ten-cent, the fifty-cent, and the one-dollar coins) are all arranged practically on one side of the plate, while the channels for the five and twenty-five cent pieces deliver into a channel Z, that conducts the coin along the back of the plate, all of these channels, however, delivering the proper coin into a certain section 2'- of the money-box.

In order to prevent any coin but the proper one from being used to operate a certain signal, a series of traps n, a, n a and n" in the under walls of each of the guideways is provided, so that any false coin-that is, one that does not properly belong in the given channel-will drop through the trap and into a runway 0, through which it will be delivered into a section z in the money-box. These coins will be lost to any one attempting to use them, and the device has the further advantage of enabling the ownerof the toll-collect-ing apparatus to determine what coins have been used in payment for services actually rendered by the telephone company. As none of the false coins strike any signal, no service is rendered by the company on account of the payment of such coins into the tollbox. All of these several coin-channels are preferably formed in a single plate of some material, as metal, that is not subject to an undue amount of change under differences of temperature or weather, and the several signals, whether bells, chimes, or other sounding devices, are all preferably supported on a single plate, which maybe conveniently fitted into any desirable form of inclosi n g box. A cover h is provided that overlies the surface of the plate it, so as to form practicallya fourth wall for the several guideways, making the channels practically tubular in form, although so long as the channels answer the function as guides that direct and control the movement of the coins it is not material how they shall be formed as to the several sides.

In the operation of my device any one wishing to use the telephone rings up the central office, asks of the operator whether the desired connection can be made with a subscriber, and if the user is answered in the affirmative he then drops the amount of toll into the proper coin-channel, and the coin striking a signal indicates to the operator at the central oflice that the proper toll has been paid, the several coins being distinguished, as has already been described, either by a given note or by a given number of signals.

I claim as my invention- 1. In a telephone-toll collector, in combination, a signal-plate having a series of coin channels or guides located side by side across the plate, a trap for the passage of the false coins formed in the walls of the coin-channel and an outlet-channel extending from such traps, and a coin-box having separate receptacles appurtenant to the serviceable and the false coins, respectively, all substantially as described.

2. In a telephone-toll collector, a signalplate having a series of coin-channels arranged in succession across the plate, and the signal-bells projecting into one or more of the separate coin-channels, all substantially as described.

3. In a telephone-toll collector, a coin-channel having an irregular surface forming the eoin-retardin g device, and two or more signalbells proj eetin g into the path of movement of the coin and between which the retarding device is located, all substantially as described.

4:. In a telephone-toll collector, in combination, a transmitter borne on an adjustable arm, an extensible tubular connection having a deflector at the upper end and extending from the transmitter to the signal-box, the signal-box containing the coin-plate and coinreceiving drawer, and the coin-plate having a series of coin-channels arranged across the plate with traps and a separate out-let for false coins, the several bells secured to the signalplate, and the money-drawer divided into compartments to receive the separate classes of coins, all substantially as described.
